CAIE chemistry — common questions
Which CAIE classes does ChemSchool cover?
Cambridge Assessment International Education chemistry is covered for IGCSE, AS Level and A Level. Each has its own notes, past papers and syllabus, kept separate so you only ever see material for your own class.
Are the CAIE chemistry notes and past papers free?
Yes. Every CAIE chapter, past paper and mark scheme on ChemSchool is free to read online or download, and you do not need an account to open them.
Which years of CAIE chemistry past papers are available?
Papers currently span 2021-2027, and new sessions are added as the board releases them. Older sessions stay online, so you can work backwards through several years.
How are the CAIE chemistry notes organised?
Notes are split by class and then chapter by chapter, following the order of the CAIE specification, so a chapter page matches a single syllabus section rather than a whole unit.
